There was several issues here:
- `self.extensions` was adding 'meta' multiple times (ref #1058)
- `self.extensions` was keeping a reference to `self.settings['MD_EXTENSIONS']`,
so adding 'meta' to it.
- the `%s_EXTENSIONS` block coming after, it was overriding `self.extensions`
with `self.settings['EXTENSIONS']` (while it was a reference, it was working,
but ...). As this is currently used only for Mardown, the simplest solution is
to remove this, and let each reader manage its `_EXTENSIONS` setting.
`get_instance()` returns two values. Old code, instead of unpacking two
values in two variables, placed the tuple in a single variable
`pelican`.
Later in the same block when `pelican.run()` was called, it resulted in
error.

Either the returned value should be unpacked properly or
`pelican[0].run` should be called.
The latest version of pip (1.4) no longer installs pre-release versions
(alpha, beta, etc.) by default. Because pytz uses an unorthodox version
number scheme, pip thinks it's a pre-release and skips it. This
change to setup.py should alleviate the problem until it is otherwise
resolved.
Add a `Readers` class which contains a dict of file extensions / `Reader`
instances. This dict can be overwritten with a `READERS` settings, for instance
to avoid processing *.html files:
READERS = {'html': None}
Or to add a custom reader for the `foo` extension:
READERS = {'foo': FooReader}
This dict is no storing the Reader classes as it was done before with
`EXTENSIONS`. It stores the instances of the Reader classes to avoid instancing
for each file reading.
